Petrolhead Colin Furze put a 125cc motorbike engine on the stroller, giving it a top speed of 50mph, and attached four gears to help it go up hills.But he has not dared drive it flat out with one-month-old Jake on board.

‘Hopefully, one day, I’ll take Jake for a ride, but I’m not sure my girlfriend, Charlotte, would be happy about it, mind,’ said Mr Furze, 33, of Stamford, Lincolnshire.

‘It is rather scary to drive but I’ve had lots of envious looks from mums and dads, especially when they are pushing their babies up hills,’ said Colin.’It is really unstable when it goes at top speed and if you hit a rough bit in the road you are in danger of falling off, but so far I’ve managed not to crash.’

‘You hear people complain about walking miles to push their new babies to sleep so I thought this would be a bit of fun,’ he added.’I needed to go at least 30mph to do the record and I managed to do much better than that which is fantastic.’I designed it with three wheels to make it easier to steer, but it’s still quite tricky.’Hopefully one day I’ll be able to take Jake for a ride in it but I’m not sure if Charlotte would be very happy about that!’
